System and method for facilitating logo-recognition training of a recognition model

ABSTRACT

In certain embodiments, training of a prediction model (e.g., recognition or other prediction model) may be facilitated via a training set generated based on one or more logos or other graphics. In some embodiments, graphics information associated with a logo or graphic (e.g., to be recognized via a recognition model) may be obtained. Training media items (e.g., images, videos, etc.) may be generated based on the graphics information, where each of the training media items includes (i) content other than the logo and (ii) a given representation of the logo integrated with the other content. The training media items may be processed via the recognition model to generate predictions (related to recognition of the logo or graphic for the training media items). The recognition model may be updated based on (i) the generated predictions and (ii) corresponding reference indications (related to recognition of the logo for the training media items).

CROSS-REFERENCE TO RELATED APPLICATIONS

The present patent application is a continuation of U.S. patent application Ser. No. 15/475,900, filed on Mar. 31, 2017, now U.S. Pat. No. 10,163,043, the entire contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

The invention relates to training of prediction models, including, for example, training of a neutral network or other recognition model to recognize a logo or other object.

BACKGROUND OF THE INVENTION

In recent years, the field of artificial intelligence and machine learning has experienced a resurgence due to advances in performance of computer hardware, sizes of training sets, theoretical understanding of artificial intelligence, and other advances. This resurgence has enabled many advances in other technical fields, including recognition or other prediction systems. One application of automated recognition systems include detection of brand logos in images and videos shared on social media or other platforms, which may be used to develop insights into the brands, including interest of users with respect to the brands and their products/services, the types of users that like (or dislike) particular brands, or other information.

In typical artificial-intelligence-based recognition systems, a recognition model is trained to recognize logos of different appearances by collecting and hand-annotating large sets of images in which the logos appear in many different settings (e.g., photographs, ads, etc.) from many different views (e.g., left-perspective billboard, front-perspective on a T-shirt, etc.) in order to encompass a wide enough variety of appearance to obtain acceptable performance. Even with computer-assisted searches, the collection of the large sets of images (in which a given logo appears) for use in training a recognition model to recognize the given logo can be resource intensive and time consuming. Moreover, a collection of large sets of images (in which a given logo appears) may be difficult or impossible to obtain via computer-assisted searches, especially when the given logo is new and has not (or has only recently) been released to the public. These and other drawbacks exist.

SUMMARY OF THE INVENTION

Aspects of the invention relate to methods, apparatuses, and/or systems for facilitating training of a neutral network or other recognition model to recognize a logo (or other graphic) or other object.

In some embodiments, logo recognition training of a recognition model may be facilitated via a media item training set generated based on one or more logos. The media item training set may include images, videos, audios, or other media items. A neutral network or other recognition model may be trained and utilized for recognizing logos. In some embodiments, in addition to, or instead of, collecting large sets of already-existing media items having representation of the logos and hand-annotating those media items to prepare them for use in training the recognition model, a small number of representations of the logos may be used to generate a large set of media items for training the recognition model to recognize the logos. In some embodiments, a large set of training media items may be generated from a small set of representations of a logo by automatically applying different transformations to a representation of the logo and combining the transformed representations of the logo respectively with other content. In some embodiments, the same transformed representation of the logo may be used to generate multiple training media items. In this way, for example, the need to perform resource-intensive and/or time-consuming computer-assisted searches to collect large sets of images for use in training a recognition model to recognize a given logo or other graphic may be reduced. Even in circumstances where large sets of already-existing media items having a representation of a specific logo may be difficult or impossible to obtain, a sufficient collection of media items may be generated to efficient train a recognition model.

Various other aspects, features, and advantages of the invention will be apparent through the detailed description of the invention and the drawings attached hereto.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. It will be appreciated, however, by those having skill in the art that the embodiments of the invention may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the embodiments of the invention.

FIG. 1 shows a system 100 for facilitating training of recognition or other prediction models, in accordance with one or more embodiments. As shown in FIG. 1, system 100 may include server(s) 102, client device 104 (or client devices 104 a-104 n), or other components. Server 102 may include item generation subsystem 112, model training subsystem 114, feedback subsystem 116, presentation subsystem 118, or other components. Each client device 104 may include any type of mobile terminal, fixed terminal, or other device. By way of example, client device 104 may include a desktop computer, a notebook computer, a tablet computer, a smartphone, a wearable device, or other client device. Users may, for instance, utilize one or more client devices 104 to interact with one another, one or more servers, or other components of system 100. It should be noted that, while one or more operations are described herein as being performed by particular components of server 102, those operations may, in some embodiments, be performed by other components of server 102 or other components of system 100. As an example, while one or more operations are described herein as being performed by components of server 102, those operations may, in some embodiments, be performed by components of client device 104.

As discussed, training a recognition model (or other prediction model) can be a challenge. While advances in the performance of computer hardware have greatly increased the capabilities of servers and networks to obtain and process data and also lowered the cost to do so, computer-assisted searches to collect large sets of images (in which a given object appears) for use in training a recognition model to recognize the object can be resource intensive and time consuming. A collection of large sets of images (in which a given object appears) may also be difficult or impossible to obtain via computer-assisted searches. As an example, it may be difficult or impossible to obtain large sets of images showing a new logo when the new logo has not been or only recently released to the public. As another example, it may be difficult to obtain larger sets of images showing a particular individual when the individual has generally avoided having his/her picture taken or when the individual avoids social media.

Training Item Generation and Model Training

In some embodiments, system 100 may facilitate object recognition training of a recognition model via a media item training set generated based on one or more objects. Such objects may include logos (or other graphics), persons, animals (e.g., non-human animals), plants, physical items, fictional characters or objects, or other objects that are to be recognized via a recognition model (e.g., a neutral network or other recognition model). The media item training set may include images, videos, audios, or other media items. In some embodiments, a neutral network may be trained and utilized for recognizing objects. As an example, neural networks may be based on a large collection of neural units (or artificial neurons). Neural networks may loosely mimic the manner in which a biological brain works (e.g., via large clusters of biological neurons connected by axons). Each neural unit of a neural network may be connected with many other neural units of the neural network. Such connections can be enforcing or inhibitory in their effect on the activation state of connected neural units. In some embodiments, each individual neural unit may have a summation function which combines the values of all its inputs together. In some embodiments, each connection (or the neutral unit itself) may have a threshold function such that the signal must surpass the threshold before it is allowed to propagate to other neural units. These neural network systems may be self-learning and trained, rather than explicitly programmed, and can perform significantly better in certain areas of problem solving, as compared to traditional computer programs. In some embodiments, neural networks may include multiple layers (e.g., where a signal path traverses from front layers to back layers). In some embodiments, back propagation techniques may be utilized by the neural networks, where forward stimulation is used to reset weights on the “front” neural units. In some embodiments, stimulation and inhibition for neural networks may be more free-flowing, with connections interacting in a more chaotic and complex fashion.

In some embodiments, system 100 may facilitate training of a recognition model to recognize one or more objects. In addition to, or instead of collecting large sets of already-existing media items having representation of the objects and hand-annotating those media items to prepare them for use in training the recognition model, a small number of representations of the objects may be used to generate a large set of media items for training the recognition model to recognize the objects. As an example, with respect to a logo (that is to be recognized by the recognition model), a single “template” image of the logo (or other small number of template images of the logo) in raster or vector format (or other format) may be used to generate training media items that each include a rendering of the logo. In one use case, the template image(s) of the logo may only include the logo on a “clean” background (e.g., transparent background, solid white background, etc.). In another use case, other types of template image(s) of the logo may be utilized to generate the training media items. The number of template images of the logo utilized to generate the training media item may be 10 or less template images of the logo, 20 or less template images of the logo, 30 or less template images of the logo, or other number of template images. The number of training media items (generated based on the template images of the logo) may be 500 or more training media items, 1000 or more training media items, 10000 or more training media items, 100000 or more training media items, 1000000 or more training media items, or other number of training media items.

In some embodiments, system 100 may use object information associated with an object (e.g., from object database(s) 134 or other source) to generate media items for training a recognition model (e.g., a neural network or the recognition model) to recognize the object. System 100 may provide the media items as input to the recognition model to train the recognition model to recognize the object (e.g., as described herein). The object information may include a data file or other data structure having data representing a representation of the object (e.g., a rendering of the object or other representation of the object), a data file or other data structure having data identifying a reference to the representation of the object (e.g., a link or other pointer to the representation of the object), or other information. In some embodiments, each of the training media items (generated based on the object information) may include a rendering of the logo. In some embodiments, each of the training media items may include (i) content other than the logo and (ii) the logo integrated with the other content. As an example, the other content may include representations of other objects (e.g., logos, persons, animals (e.g., non-human animals), plants, physical items, fictional characters or objects, etc.), background or foreground content, watermarks, randomly-generated content, or other aspects.

In some embodiments, with respect to training a recognition model to recognize an object, system 100 may generate a large set of training media item from a small set of representations of the object by automatically applying different transformations to a representation of the object (e.g., a rendering or other representation of the object) and combining the transformed representations of the object respectively with other content (e.g., background images, representations of other objects, randomly-generated patterns or content, etc.). In some embodiments, the same transformed representation of the object may be used to generate multiple training media items (e.g., the same transformed representation of the object combined with different background images, different representations of other objects, different randomly-generated patterns or content, etc.). In some embodiments, the automatic application of the different transformations may include randomized transformations to a representation of the object. In some embodiments, the randomized transformation may be a pseudorandomized transformation (e.g., by executing one or more RdRand instructions and applying one or more seed values or via other randomization techniques). In this way, for example, the need to perform resource-intensive and/or time-consuming computer-assisted searches to collect large sets of images for use in training a recognition model to recognize a given object may be reduced. As another example, even in circumstances where large sets of already-existing media items having a representation of a specific object may be difficult or impossible to obtain, system 100 may enable media items to be obtained (e.g., automatically generated) to train a recognition model. In some embodiments, media items generated by system 100 for training a recognition model may be tuned to resemble those that would typically be found in one or more application settings (e.g., different photographs, advertisements, etc.).

In some embodiments, item generation subsystem 112 may generate media items based on object information associated with an object (e.g., a rendering or other representation of the object) or other information such that the media items respectively include representations of the object or other content with which the object is integrated. As an example, FIGS. 2A-2F illustrate media items (e.g., images) generated from a representation of an object (e.g., a logo). In one use case, with respect to FIGS. 2A-2F, a data file of the logo (e.g., a file representing a rendering of the logo) may be used to generate images 202 a-202 f for use in training a recognition such that each of images 202 a-202 f include a logo rendering 204 (e.g., logo rendering 204 a-204 f). In another use case, each of the logo renderings 204 a-204 f may be integrated with one or more background images (e.g., different images of a person wearing a t-shirt without the logo) to generate new images (e.g., images of a person wearing a t-shirt with the logo) for use in training a recognition model to recognize the logo.

In some embodiments, item generation subsystem 112 may obtain one or more transformation parameter sets (e.g., from template content database(s) 136 or other source) and generate media items based on (i) object information associated with an object, (ii) the transformation parameter sets, or (iii) other information. Model training subsystem 114 may process, via a recognition model, the generated media items to train the recognition model to recognize the object. In some embodiments, each of the transformation parameter sets includes parameters different from one or more other ones of the transformation parameter sets and/or parameters that are the same as parameters of one or more other ones of the transformation parameter sets. The transformation parameter sets may include sharpening parameters (e.g., for adjusting sharpness of object representation or other content), softening parameters (e.g., for adjusting softness of object representation or other content), brightness parameters (e.g., for adjusting brightness of object representation or other content), contrast parameters (e.g., for adjusting contrast of object representation or other content), recoloring parameters (e.g., for recoloring an object representation or other content), or other transformation parameters.

Additionally, or alternatively, the transformation parameter sets may include blurring effect parameters (e.g., for adding blurring effects to an object representation or other content), camera effect parameters (e.g., for adding camera effects to an object representation or other content), motion effect parameters (e.g., for adding motion effects to an object representation or other content), shadow effect parameters (e.g., for adding shadow effects to an object representation or other content), pattern effect parameters (e.g., for adding pattern effects to an object representation or other content), texture effect parameters (e.g., for adding texture effects to an object representation or other content), or other transformation parameters. As an example, camera effects may include matte painting, Schüfftan process, forced perspective, dolly zoom, lens flares, lighting effects, filtration (e.g., using a fog filter to simulate fog, a grad filter to simulate sunset, etc.), shutter effects, time-lapse, slow motion, fast motion, speed ramping, bipacks, slit-scan, infrared photography, reverse motion, front projection, rear projection, phonotrope, or other camera effects. In one scenario, with respect to FIG. 2D, shadow effect parameters indicating adding a shadow effect to a particular rendering of a logo (e.g., rendering 204 a or 204 c) may have been applied to the particular logo rendering to generate logo rendering 204 d.

Additionally, or alternatively, the transformation parameter sets may include rotation parameters (e.g., for rotating an object representation or other content), perspective parameters (e.g., for adjusting a perspective view of an object representation or other content), resizing parameters (e.g., for resizing an object representation or other content to simulate effects of scale), compression parameters (e.g., for compressing a data file or other structure representing an object representation or other content to reduce file/structure size), deletion parameters (e.g., for removing from view a portion of an object representation or other content), occlusion parameters (e.g., for making transparent or hiding a portion of an object representation or other content), or other transformation parameters.

In one use case, resizing parameters indicating adjusting a size of a particular rendering of a logo (e.g., rendering 204 c) may have been applied to the particular logo rendering to generate logo rendering 204 a. In another use case, with respect to FIGS. 2B and 2E, different rotation parameters indicating rotating of a particular rendering of a logo (e.g., rendering 204 a or 204 c) may have been applied to the particular logo rendering to respectively generate logo renderings 204 b and 204 e. In a further use case, different perspective parameters indicating adjustment of a perspective of a particular rendering of a logo (e.g., rendering 204 a or 204 c) may have been applied to the particular logo rendering to respectively generate logo renderings 204 b and 204 e. In another use case, with respect to FIG. 2F, one or more deletion or occlusion parameters indicating removal or hiding of a portion of a particular rendering of a logo (e.g., rendering 204 a or 204 c) may have been applied to the particular logo rendering to generate logo rendering 204 f (e.g., where portions of the “G” and the second “0” are removed or hidden). Such transformations of a single representation of an object (or small number of representations of the object) may, for example, allow system 100 to generate a large set of object representations (e.g., 100 or more, 500 or more, 1000 or more, 10000 or more, 100000 or more, 1000000 or more, etc.) and/or combine at least some of those object representations with other content to generate one or more large sets of media items (e.g., 500 or more, 1000 or more, 10000 or more, 100000 or more, 1000000 or more, 10000000 or more, etc.).

In some embodiments, item generation subsystem 112 may obtain one or more transformation parameter sets by randomly generating the transformation parameter sets, and item generation subsystem 112 may generate media items based on (i) object information associated with an object, (ii) the transformation parameter sets, or (iii) other information. In some embodiments, item generation subsystem 112 may randomly generate the transformation parameter sets by randomly obtaining transformation parameters for each of the transformation parameter sets (e.g., via random generation of transformation parameters for each of the transformation parameter sets, via random selection of the transformation parameters for each of the transformation parameter sets from a larger set of transformation parameters, etc.). In some embodiments, the randomization may be pseudorandom (e.g., by executing one or more RdRand instructions and applying one or more seed values or via other randomization techniques to randomly obtain the transformation parameters).

In some embodiments, item generation subsystem 112 may obtain template media items (e.g., from template content database(s) 136 or other source) and generate media items (for use in training a recognition model to recognize an object) by integrating representations of the object with the template media items. Such template media items may include images, videos, audios, or other media items. As an example, one or more representations of the object may be transformed (e.g., as described herein) to generate transformations of those object representations. For each of a plurality of template media items, item generation subsystem 112 may generate one or more training media items by integrating one or more transformed representations (or untransformed representations) with the template media item. In some embodiments, integration of one or more representations of an object (e.g., untransformed or transformed object representations) with a template media item may comprise (i) alpha-blending the object representations with the template image, (ii) inserting multiple copies or multiple different ones of the object representations on the template image (e.g., such that a media item generated from the multiple insertions includes multiple representations of the object), or (iii) performing other integration techniques.

Model Training Via Reference Feedback

In some embodiments, upon obtaining a set of media items (e.g., via techniques as described herein) for training a recognition model (e.g., a neural network or other recognition model) to recognize one or more objects, system 100 may process the media items via the recognition model to generate predictions related to recognition of the objects with respect to the processed media items (e.g., how the recognition believes the objects should be labeled, where the recognition model believes the objects are located within the media items, or other predictions). System 100 may analyze those predictions against a set of reference feedback, such as reference labels describing the objects to be recognized respectively in one or more of the processed media items, reference indications of locations of the objects to be recognized respectively in the processed media items, or other desired outputs for use as a reference. In one use case, the reference outputs may be provided as input to the recognition model (e.g., prior to, simultaneously with, or subsequent to providing the training media items to the recognition model), which the recognition model may utilize to determine whether its predictions are accurate, determine the level of accuracy or completeness with respect to each prediction, or other make other determinations (e.g., via deep learning through its multiple layers of abstraction or other techniques). Such determinations may be utilized by the recognition model to improve the accuracy or completeness of its object recognition capabilities. In another use case, accuracy or completeness indications with respect to the recognition model's predicted labels, predicted location indications, or other predictions (e.g., whether a given prediction is accurate, how accurate or complete a given prediction is, etc.) may be provided to the recognition model, which, in turn, may utilize the accuracy or completeness indications to improve the accuracy or completeness of its object recognition capabilities.

In some embodiments, model training subsystem 114 may provide a set of media items (that include one or more objects to be recognized) as input to a recognition model, which, in turn, may output its predicted class labels, bounding boxes, heat maps, or other predictions with respect to the objects or other aspects of the media items. In some embodiments, model training subsystem 114 may train the recognition model by constraining the training media items to a limited receptive field (e.g., in which the object(s) to be recognized makes up a significant or majority portion of the training media items). Additionally, or alternatively, model training subsystem 114 may train the recognition model at multiple scales (e.g., training media items having different sizes of the same object or having representations of the object at different locations within the training media items) to help the recognition model recognize logos at different positions and sizes. In some cases, each training iteration may increase the number of different sizes or positions of the representation of the object (e.g., up to a threshold number of iterations or other bound). In some cases, each training iteration may decrease the number of different sizes or positions of the representations of the object (e.g., up to a threshold number of iterations or other bound).

In some embodiments, prior to, simultaneously with, or subsequent to providing a set of media items to a recognition model for processing, feedback subsystem 116 may provide the recognition model with reference labels describing one or more object to be recognized in one or more of the processed media items, reference indications of locations of the objects to be recognized in the processed media items, or other desired outputs for use as a reference. As indicated, the generated predictions may include labels of the objects respectively predicted to be in the processed media items (e.g., class labels or other labels describing the predicted objects), indications of predicted locations of the predicted objects (e.g., heat or other maps, boundary boxes or other structures, etc., indicating the predicted locations), or other predictions. As indicated, the recognition model may utilize such reference outputs to improve the accuracy or completeness of its object recognition capabilities.

In some embodiments, presentation subsystem 118 may cause one or more predictions of a recognition model to be presented on a user interface to obtain user feedback. Feedback subsystem 116 may obtain user feedback with respect to a prediction (e.g., a binary feedback indicating accurate or not accurate, a user input identifying a label of an object, a user input identifying a location of the object, or other feedback) and provide the user feedback to the recognition model. In response, the recognition may utilize the user feedback to update itself to acknowledge or reflect the user feedback. In one scenario, the user feedback may include “Correct” or “Not Correct” with respect to the recognition model's prediction of a label for an object predicted to be in a processed media item. In another scenario, the user feedback may include “Brand X” with respect to the recognition model's prediction of a label “Brand Y” for a Brand X logo in a processed media item (e.g., thus, indicating to the recognition model that its prediction was not accurate as well as provide the recognition model with the user-provided label for consideration). In another scenario, the user feedback may include moving or resizing the recognition model's boundary box that it assigned to an particular area of a processed media item to another area of the processed media item (e.g., smaller area, another location, etc.), thereby indicating to the recognition model that its prediction was not accurate or not complete as well as provide the recognition model with the user-indicated area for consideration).

Examples Flowcharts

FIGS. 3 and 4 are example flowcharts of processing operations of methods that enable the various features and functionality of the system as described in detail above. The processing operations of each method presented below are intended to be illustrative and non-limiting. In some embodiments, for example, the methods may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the processing operations of the methods are illustrated (and described below) is not intended to be limiting.

In some embodiments, the methods may be implemented in one or more processing devices (e.g., a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The processing devices may include one or more devices executing some or all of the operations of the methods in response to instructions stored electronically on an electronic storage medium. The processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of the methods.

FIG. 3 shows a flowchart of a method 300 of facilitating object recognition training of a recognition model via a media item training set generated based on one or more objects, in accordance with one or more embodiments. In an operation 302, object information associated with an object may be obtained. As an example, the object may include a logo or other graphic, a person, an animal (e.g., non-human animal), a plant, a physical item, a fictional character or object, or other object that is to be recognized via a recognition model (e.g., a neural network or other recognition model). The object information may include a data file or other data structure having data representing a representation of the object (e.g., a rendering of the object or other representation of the object), a data file or other data structure having data identifying a reference to the representation of the object (e.g., a link or other pointer to the representation of the object), or other information. Operation 302 may be performed by an item generation subsystem that is the same as or similar to item generation subsystem 112, in accordance with one or more embodiments.

In an operation 304, training media items may be generated based on the object information. The training media items may include audio, images, videos, or other media items (e.g., other media items representing one or more aspects of the object). As an example, the training media items may be generated such that each of the training media items comprises (i) content other than the object, (ii) a given representation of the object integrated with the other content, or (iii) other information. In one use case, the training media items may be generated such that each of the training media items are different from one another in appearance, computational resource size (e.g., different file sizes due to different compression levels applied or other techniques), or other aspects. In another use case, the training media items may be generated such that at least one of the training media items has a different transformed representation of the object from at least one other one of the training media items. Operation 304 may be performed by an item generation subsystem that is the same as or similar to item generation subsystem 112, in accordance with one or more embodiments.

In an operation 306, the training media items may be processed via the recognition model to generate predictions (related to recognition of the object for the training media items). As an example, the generated predictions may include labels of one or more objects respectively predicted to be in the training media items (e.g., class labels or other labels describing the predicted objects), indications of predicted locations of the predicted objects (e.g., heat or other maps, boundary boxes or other structures, etc., indicating the predicted locations), or other predictions. Operation 306 may be performed by a model training subsystem (e.g., via the recognition model) that is the same as or similar to model training subsystem 114, in accordance with one or more embodiments.

In an operation 308, a reference feedback set may be obtained. As an example, the reference feedback set may include reference indications (related to recognition of the object for the training media items). The reference indications may include (i) one or more reference labels describing the object to be recognized respectively in one or more of the training media items, reference indications of locations of the object to be recognized respectively in the training media items, or other desired outputs for use as a reference (ii) accuracy or completeness indications with respect to the recognition model's predicted labels, predicted location indications, or other predictions (e.g., whether a given prediction is accurate, how accurate or complete a given prediction is, etc.), or (iii) other indications for use as a reference. In one use case, the reference outputs may be provided as input to the recognition model (e.g., prior to, simultaneously with, or subsequent to providing the training media items to the recognition model), which the recognition model may utilize to determine whether its predictions are accurate, determine the level of accuracy or completeness with respect to each prediction, or other make other determinations. Such determinations may be utilized by the recognition model to improve the accuracy or completeness of its object recognition capabilities. Operation 308 may be performed by a feedback subsystem that is the same as or similar to feedback subsystem 116, in accordance with one or more embodiments.

In an operation 310, the recognition model may be updated based on the generated predictions and the reference feedback set. As an example, where the reference feedback set includes one or more reference labels describing the object to be recognized, reference indications of locations of the object to be recognized respectively in the training media items, or other desired outputs for use as a reference, the reference outputs may be used by the recognition model to determine whether its generated predictions are accurate or the level of accuracy or completeness of its generated predictions (e.g., by comparing one or more aspects of a given generated prediction with its corresponding reference output or via other techniques). In one use case, the recognition model may utilize such determinations to update itself (e.g., in parallel with the recognition model's processing of a given set of training media items to recognize objects in the training media items, after the recognition model's processing of the given set of training media items, etc.). Operation 310 may be performed by a model training subsystem (e.g., via the recognition model) that is the same as or similar to model training subsystem 114, in accordance with one or more embodiments.

FIG. 4 shows a flowchart of a method 400 of facilitating logo recognition training of a neural network via an image training set generated based on one or more logos, in accordance with one or more embodiments. In an operation 402, logo information associated with a logo (that is to be recognized via a neutral network) may be obtained. As an example, the logo information may include a data file or other data structure having data representing a rendering of the logo, a data file or other data structure having data identifying a reference to the rendering of the logo (e.g., a link or other pointer to the logo rendering), or other information.

In one use case, the training images may be generated such that each of the training images are different from one another in appearance, computational resource size (e.g., different file sizes due to different compression levels applied or other techniques), or other aspects. In another use case, the training images may be generated such that at least one of the training images has a different transformed rendering of the logo from at least one other one of the training images.

In one use case, the reference outputs may be provided as input to the neural network (e.g., prior to, simultaneously with, or subsequent to providing the training images to the neural network), which the neural network may utilize to determine whether its predictions are accurate, determine the level of accuracy or completeness with respect to each prediction, or other make other determinations. Such determinations may be utilized by the neural network to improve the accuracy or completeness of its logo recognition capabilities. Operation 410 may be performed by a feedback subsystem that is the same as or similar to feedback subsystem 116, in accordance with one or more embodiments.

In an operation 412, the neural network may be updated based on the generated predictions and the reference feedback set. As an example, where the reference feedback set includes one or more reference labels describing the logo to be recognized, reference indications of locations of the logo to be recognized respectively in the training images, or other desired outputs for use as a reference, the reference outputs may be used by the neural network to determine whether its generated predictions are accurate or the level of accuracy or completeness of its generated predictions (e.g., by comparing one or more aspects of a given generated prediction with its corresponding reference output or via other techniques). In one use case, the neural network may utilize such determinations to update itself (e.g., in parallel with the neural network's processing of a given set of training images to recognize logos in the training images, after the neural network's processing of the given set of training images, etc.). Operation 412 may be performed by a model training subsystem (e.g., via the neural network) that is the same as or similar to model training subsystem 114, in accordance with one or more embodiments.
